rnas'rnnnn's HAND GUARD.

Application filed August 24, 1 925. Serial, No. 52,080.

To all whom it may concern:

Be it known that I, Josnrr-r I. VINZANT,

a citizen of the United States, residing at Inglewood, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in Plasterers Hand Guards, of which the following is aspecification.

My invention is a plasterers hand guard adapted to be attached to atrowel to protect the plasterers hands from the injurious effects ofcement and lime," particularly when used in placing a cement stucco. Myhand guard is also applicable to a masons trowel if so desired.

An object of my invention is to provide a simple covering which may bereadily at.

tached and detached from a trowel and form an effective covering toprotect the hand which is particularly necessary when applying cementmortar as the cement is much more injurious to the plasterers' handsthan is a lime mortar. terers utilize cotton gloves which in ordinarywork will only last for one day and moreover frequently become saturatedwith the water from the cement mortar injuring the hands through theglove. 7

My hand guard is preferably made of 3 molded rubber adapted to fit overthe handle of a plasterers trowel, leaving suflicient space to readilygrasp the handle and with the covering forming a guard coming well upover the back of the hand tothe wrist. r I also provide the guard withan opening at the back to provide sufficient ventilation to keep thehand cool. The molded rubber is provided with an aperture in the lowerfront end, which may be stretched to pass over the handle and engage theiron stem connected to the trowel and the rear end of the device iseither connected directly to the end of the handle by a clamp bolt or byhaving a wire loop forming the connecting member to hold the base spreadalong the trowel.

My invention will be more readily understood from the followingdescription and drawings, in which: Figure 1 isa perspective view of myhand guard attached to a plasterers trowel, showing what I may designateas the shoe-shaped guard.

Fig. 2 is a longitudinal section of the hand guard of Fig. 1.

At present most plas-v Fig. 3 is a transverse section on the line 3-3 ofFig. 2. I

Fig. 4 1s a perspective View of a modified type of hand g11ardsh0wing amore complete covering than the structure of Fig. 1

and with a freer opening at the rear for ventilation. r I

Fig. 5 isa longitudinal section of the guard of Fig. 4. l

Fig. 6 is a Figs- 4 and 5 showing therubber fabric of the base engagingthe rear end of the handle instead of the wire loop.

In the drawings, the trowel illustrated is of the type known as aplasterers trowel having the usual flatblade 1, a central reinforcingbar2, a stem 3 extending upwardly therefrom and a wooden handle 4connected to the stem 3. The trowel maybe of any ordinary type. i

The hand guard shown in Figs. 1 to 3 of the shoe-shaped type ispreferably formed of amolded rubber fabric somewhat in the form of ashoe, as indicated by numeral 5,, having a base section 6, a toe section7, a"

heel-strap 8, side sections 9 and an upper rim IO-through which the handmay be inthe adjacent rubber fabric so that it may pass over the rearend 15 of the handle 4 and downwardly on the stem 8. Theheelmodification of the guard of section is also formed with an aperture 16also preferably having a reinforcing rim 1? through which 18 inserted abolt--18 with a screw threaded end on which is fasteneda 11116119preferably with a washer20 bearing on the rubber of theheel "strap. Insome types of trowels the horizontal portion of the stem passes throughthe handle and has a nuton' the rear end which may be utilized,

if not a bolt may be, fitted or screwed into the rear end of the handle.Any other suitable type of fastening to securethe heel strap in placewould be suitable.

In the construction of Figs. at and 5, the various details abovedescribed are somewhat similar, particularly in regard to the type of.aperture 13, however the horizontal type of heel strap is discarded. Thebase of the hand guard at its rear end is provided with a loop 21 byturning a strap end 22 back on itself and securing it to the fabric atthe base. A wire strap 23 extends from the loop 21 and is attached tothe rear of the handle by means of a bolt and nut similar to those usedin connection with Figs. 1 to 3. In detail this strap is shown as beingformed by a short piece of wire bent into a flat ring-24c, threadedthrough the loop 21, astraight section 25 and an eye 26 engaged by thebolt and nut.

It is believed that the-manner. of securing the guard of Figs. 4 and 5to a trowel handle is obvious, the aperture 13 being stretched andfitted over the handle and stem in the same manner as described inconnection with Figs. 1 to 3. The wire strap 23'is connected over theend of the bolt and the" end of the handle as above described. In thisform of hand guard the top portion 27 can be extended rearwardly furtheron the handle than in the construction of Figs. 1 to 3 and the rim 28forming the edge for the top, sides and base of the guard ma be made toform a fairly tight fit around the wrist. This type of guardisparticularly suitable for applying stuccoplaster to outside walls asthe hands are better-protected from the falling plaster and frointheslopping of any cement water.

In the construction of Fig. 6, the same type of guard is'usedas shown inFigs. d and- 5 except that a strap 29 formed integral with the basesection and being, an extension thereof isturned up to engage the boltand nut, having anaperture therethrough the same as the heel strap 8of'Figs. 1 to 3. This strap may likewise be designated'as aheel strap asit is positioned at the heel: end of the hand guard.

My invention may be considerably moditied in general construction and inspecific features to suit diiterent'typesof trowels suchas a masons"trowel orother types of plasterers trowels. The type of hand guard mayalso be considerably modified in detail without departing from thespirit of my invention. for instance. if desired the guard could be madeof non-resilient material and have the aperture such as 13 closed by aflap or the like which would button over and secure the two partstogether,.l":orming a fairly tight closure sutficient to prevent waterentering around the stem.

Many other changes in detail will be apparent.

It will be noted in reference to Figs. 4:. 5 and 6 that the wire strap23 and the integral strap 29 have substantially the same function. Thewire strap however, allows a freer opening for ventilation. Moreover, insome types of work where it is necessary to have freer ventilation tocool the hand the top portion 27 may be considerably cut away.

Having described my invention, what I claim is:

1. A plasterers hand guard comprising in combination a trowel having astem and a handle, the hand guard formed of flexible material having anaperture through the base adapted to fit over the stem and means tosecure the rear end of the hand guard to the rear end of the handle, theguard extending partly over the said handle.

2. A plasterers hand guard comprising in combination a trowel having astem and a handle, a hand guard formed of flexible material having anaperture therethrough in the base, resilient material adjacent theaperture, thehand guard having a base secvion adapted to extend alongthe trowel, side sections to extend up the sides of the handle, a topsection to extend over the top of the handle and means to secure therear end of the hand guard. tothe rear end of the handle.

3. A plasterershand guard composed of flexible material shaped to fitover a persons-hand when holding a trowel and having an aperture throughthe lower surface, flexihie materialadjacent the aperture to allow theguard to he slipped over the handle and stem of a trowel and means onthe rear end of the hand guard to attach to the rear end of the trowelhandle.

at. A plasterers hand guard as claimed in claim 3', having in additionan opening formed near the rear end of the handle to allow ventilation.

5. A plasterers hand guard formed of fl'exiblematerial shaped to fitover a hand in grasping a trowel handle, said guard having an aperturethrough the lower surface, flexible material adjacent the aperture toallow stretel'iing to pass over a handle and engage the stem of atrowel, aheel strap at the rear end of the guard adapted to engage therear end of the handle of atrowel.

6. A'plastcrers hand guard as claimed in claim 5. in which the heelstrap is in the form of a wire having a loop attached to the guard andaneye secured to the rear end of the handle of the trowel.

7. A plasterers hand guard as. claimed in claim 5, in which the strap isin the form of a wire, the wire having a flat ring at the lower end andthe hand guard having a rearward extension with a loop formed therein,the ring of the strap and the loop of the guard interlocking, the handlehaving a bolt engaging an eye of the strap.

8. A plasterers hand guard formed of flexible material shaped to fitover a hand in grasping a trowel handle, said guard having an aperturethrough the lower surface, flexible material adjacent the aperture toallow stretching to pass over a handle and engage the stem of a trowel,a flexible means attached to the rear end of the guard and connected totherear end of the handle, said means being adapted to pivot on the endof the handle transversely and to allow front 10 and back movement ofthe hand guard.

In testimony whereof I have signed my name to this specification. v
